    <p>With the threshold plugin, you can apply a specific color to
    the part of a data series below a threshold. This is can be useful
    for highlighting negative values, e.g. when displaying net results
    or what's in stock.</p>

    <p class="controls">
    <input type="button" value="Threshold at 5">
    <input type="button" value="Threshold at 0">
    <input type="button" value="Threshold at -2.5">
    </p>

<script type="text/javascript">
$(function () {
    var d1 = [];
    for (var i = 0; i <= 60; i += 1)
        d1.push([i, parseInt(Math.random() * 30 - 10)]);

    function plotWithOptions(t) {
        $.plot($("#placeholder"), [ {
            data: d1,
            color: "rgb(30, 180, 20)",
            threshold: { below: t, color: "rgb(200, 20, 30)" },
            lines: { steps: true }
        } ]);
    }

    plotWithOptions(0);
    
    $(".controls input").click(function (e) {
        e.preventDefault();
        var t = parseFloat($(this).val().replace('Threshold at ', ''));
        plotWithOptions(t);
